You have gone from the sublime to the ridiculous. Assuming the pressure would stay at the maximum long enought to fill the tank, how do I get past the city code height limit of 40 feet. Also, since the local residents got an injunction and required that an American flag pole be removed because it was too noisy, I doubt that they will agree to a storage tank standing in the back yard. I don’t think I could conceal it as a kid’s doll house. People ask questions at this forum expecting reasonable answers, not hypothetical ones such as two mile long 6″ water mains to a residence, (as you replied in one previous posting), or 178 foot water towers.
